Abstract

The invention discloses a method for controlling rotating speed of an emergency fan-wing of a fan-wing aircraft, and relates to the technical field of fan-wing aircrafts. The method comprises the following steps that firstly, a controller is used for judging the fault of the rudder surface of the fan-wing aircraft, if the judgment result is an elevator fault in single-rudder-surface faults, a first control scheme is executed; if the judgment result is an aileron rudder fault in single-rudder-surface faults, a second control scheme is executed; if the judgment result is a rudder fault in the single-rudder-surface faults or a transverse lateral fault in a plurality of rudder surface faults, a third control scheme is executed; and if the judging result is the longitudinal and transverse lateral faults in the plurality of rudder surface faults, a fourth control scheme is executed. According to the method, the low efficiency or fault phenomenon of the fan-wing aircraft operating the ruddersurface can be coped well with, and safe and stable flight of the fan-wing aircraft is ensured.

Description

technical field

[0001] The invention relates to the technical field of fan-wing aircraft, in particular to the technical field of a method for controlling the emergency fan-wing speed of the fan-wing aircraft. Background technique

[0002] The fan-wing aircraft is a new-principle new-configuration aircraft that embeds a cross-flow fan on the leading edge of a large thick wing, and provides lift and thrust at the same time through the rotation of the fan. It is a low-speed and heavy-load aircraft between helicopters and fixed-wing aircraft. Due to the simple structure and control of fan-wing aircraft, it has the advantages of high flight efficiency, high load, low noise, and ultra-short take-off and landing. It has gained great development advantages in civil and military use, and has become a new research hotspot in the field of aircraft in recent years. At present, fan-wing aircraft can already complete remote control flight, but the research hotspots of fan-wing aircraft ...
